Is it possible to combine 2 or more textures VIA - BelnderKit add-on
Thanks to Nascent for the awnser.
You just add a new image texture node. Click new and name it. Then add that to the 'fac' of the MixRGB node. Then all you have to do is go into the texture paint tab and make sure you have your new texture selected (I named mine Dirt_Path_PAINT) and draw over your texture in the UV section or for easy use right in the viewport!
